block: remove the osdblk driver

2017-04-19T15:10:51+00:00

This was just a proof of concept user for the SCSI OSD library, and never had any real users. Signed-off-by: Christoph Hellwig Acked-by: Boaz Harrosh Signed-off-by: Jens Axboe

remove the mg_disk driver

2017-04-14T20:00:49+00:00

This drivers was added in 2008, but as far as a I can tell we never had a single platform that actually registered resources for the platform driver. It's also been unmaintained for a long time and apparently has a ATA mode that can be driven using the IDE/libata subsystem.

remove the obsolete hd driver

2017-04-05T15:50:34+00:00

This driver is for pre-IDE hardisk that are only found in PC from the stoneage of personal computing, and which we don't support elsewhere in the kernel these days. It's also been marked broken forever. Signed-off-by: Christoph Hellwig Reviewed-by: Martin K. Petersen Signed-off-by: Jens Axboe

drivers:block: cpqarray clean up

Commit d436641439e0 ("cpqarray: remove it from the kernel") removes the Kconfig option BLK_CPQ_DA and cpqarray. Remove the dead build rule in the Makefile. Signed-off-by: Valentin Rothberg Signed-off-by: Jens Axboe

nvme: move to a new drivers/nvme/host directory

2015-10-09T16:40:37+00:00

This patch moves the NVMe driver from drivers/block/ to its own new drivers/nvme/host/ directory. This is in preparation of splitting the current monolithic driver up and add support for the upcoming NVMe over Fabrics standard. The drivers/nvme/host/ is chose to leave space for a NVMe target implementation in addition to this host side driver.

libnvdimm, pmem: move pmem to drivers/nvdimm/

drivers/block/pmem: Add a driver for persistent memory

2015-04-01T15:03:56+00:00

PMEM is a new driver that presents a reserved range of memory as a block device. This is useful for developing with NV-DIMMs, and can be used with volatile memory as a development platform. This patch contains the initial driver from Ross Zwisler, with various changes: converted it to use a platform_device for discovery, fixed partition support and merged various patches from Boaz Harrosh.

zram: promote zram from staging

2014-01-31T00:56:55+00:00

Zram has lived in staging for a LONG LONG time and have been fixed/improved by many contributors so code is clean and stable now. Of course, there are lots of product using zram in real practice. The major TV companys have used zram as swap since two years ago and recently our production team released android smart phone with zram which is used as swap, too and recently Android Kitkat start to use zram for small memory smart phone. And there was a report Google released their ChromeOS with zram, too and cyanogenmod have been used zram long time ago. And I heard some disto have used zram block device for tmpfs. In addition, I saw many report from many other peoples. For example, Lubuntu start to use it. The benefit of zram is very clear. With my experience, one of the benefit was to remove jitter of video application with backgroud memory pressure. It would be effect of efficient memory usage by compression but more issue is whether swap is there or not in the system. Recent mobile platforms have used JAVA so there are many anonymous pages. But embedded system normally are reluctant to use eMMC or SDCard as swap because there is wear-leveling and latency issues so if we do not use swap, it means we can't reclaim anoymous pages and at last, we could encounter OOM kill. :( Although we have real storage as swap, it was a problem, too. Because it sometime ends up making system very unresponsible caused by slow swap storage performance. Quote from Luigi on Google "Since Chrome OS was mentioned: the main reason why we don't use swap to a disk (rotating or SSD) is because it doesn't degrade gracefully and leads to a bad interactive experience. Generally we prefer to manage RAM at a higher level, by transparently killing and restarting processes. But we noticed that zram is fast enough to be competitive with the latter, and it lets us make more efficient use of the available RAM. " and he announced. http://www.spinics.net/lists/linux-mm/msg57717.html Other uses case is to use zram for block device. Zram is block device so anyone can format the block device and mount on it so some guys on the internet start zram as /var/tmp. http://forums.gentoo.org/viewtopic-t-838198-start-0.html Let's promote zram and enhance/maintain it instead of removing.
